Lol. Sadly I’m not up to speed on the Boeing fleet capabilities so much these days. Can you do common fleet flying between the 787 and the 777X? Is that on the table as an option from Boeing? I know they’re the same endorsement on the license but not sure beyond that.
Yes same endorsement. I’ve been led to believe both can be flown, just like the Airbus types.
Although I’ve never flown a 777 they are procedurally identical, apparently. As an example, on the 787 the hydraulic pumps are turned on in a particular sequence. For the 787 it makes no difference and they could be turned on in any sequence, but the sequence is mandated to comply with the common endorsement as it matters in the 777 which order they’re switched on.
